If the reader can doubt of the condition of the brain in this case, he is requested to turn to the pathology, where the morbid appearances on dissection are detailed. Slowness of the pulse, with severe and obstinate pain in the head, attended with confusion of mind, is always a highly dangerous-symptom: it invariably denotes intense cerebral disease. Whenever there is such a struggle, as this case exhibits, between the physician and the disease, the disease is sure to conquer. For if the physician, terrified at the name or the duration of the malady, while he resolve to use the lancet, hesitate to employ it to the extent of subduing the disease by the first bleedings, the patient is lost. The partial relief afforded by partial measures is most delusive. The malady speedily recovers its lost strength: the patient never does. There is no practitioner who is capable of being taught by experience that can reflect on the history and progress of such a case as this, on the temporary relief afforded by such treatment, on its ultimate failure, and on the appearances presented on dissection, without regretting that more blood was not taken on the 15th and 16th days, and without at the same time resolving, that the aid he offers in future, under similar circumstances, shall be more decisive. The diminution of the pain of the head on the 22d, accompanied with increasing confusion and dullness, with a tongue growing more and more foul, and with a pulse only at 72, might well excite alarm; and accordingly, on the following day, the case was utterly without hope.
